MAX
Maximum Value
MAX.U
Maximum Value Unsigned
Description
If the contents of data register D[a] are greater than the contents of either data register D[b] (instruction format RR)
or const9 (instruction format RC), then put the contents of D[a] in data register D[c]; otherwise put the contents of
either D[b] (format RR) or const9 (format RC) in D[c]. The operands are treated as either signed (MAX) or unsigned
(MAX.U) 32-bit integers.
MAXD[c], D[a], const9 (RC)
D[c] = (D[a] > sign_ext(const9)) ? D[a] : sign_ext(const9);
MAXD[c], D[a], D[b] (RR)
D[c] = (D[a] > D[b]) ? D[a] : D[b];
MAX.UD[c], D[a], const9 (RC)
D[c] = (D[a] > zero_ext(const9)) ? D[a] : zero_ext(const9); // unsigned
MAX.UD[c], D[a], D[b] (RR)
D[c] = (D[a] > D[b]) ? D[a] : D[b]; // unsigned
